dc.description.abstractIn contrast to the common practice of evaluating heat sinks with inline or standard staggered fin placement, this research investigated the thermo-hydraulic performance of conical pin-fin heat sinks with staggered-(CPFHSst) and modified staggered-(CPFHSmst) fin placements. The heat sinks with cross-cut pin-fins oriented parallel-(CCPFHSpar) and perpendicular-(CCPFHSperp) to the airflow and a flat heat sink (FHS) are also used for com-parison. The effect of heat sink fin placement on the parameters became remarkable with increasing Re, so the modified staggered fin placement was 2-7 degrees C lower than the staggered surface and junction temperatures. Rth of the modified model compared to the staggered was 5.3 %, 5.8 %, and 3.5 % lower, while the highest Delta P is in CCPFHSperp with 6.7, 6.9, and 7.4 Pa. CCPFHSperp provided a 29.9 % advantage of Nu to the modified model, whereas the modified model provided a 6.4 % over CCPFHSperp and a 17.4 % over the staggered model for the test powers. The modified model provides the highest THP performance, with a 13.3 % advantage over CCPFHSperp, 12 %, and 10.9 % over the staggered model for the test powers. The CPFHSmst is superior regarding thermo-hydraulic performance and is an appropriate option among many heat sink models in the literature.
